Product Description
Petroleum Chemical Industry ASTM A 204 Grade B C Boiler Alloy Steel Sheet Plate
Product Information
HDT has advanced medium-heavy plate production process and state-of-the-art facilities,and can produce big concast slab(450x(1400—2600)mm) and big ingot (60tons) .Maximum thickness of structural plate: 610mm.Main grades include: Q235, Q345, Q390, A36, A572Gr42/50, A633D； S235, S275, S355 (CE approved thickness range from 6-350mm),SS490, SM490.A11 grades included in Japanese standard (JIS G310 K JIS G3106) obtained JIS approval ;S355G2-G10+N in European standard got GL approval and its max thickness reached 90mm.Among which, S355 series are widely used for manufecturing wind towers globally, approved by Siemens, Vistas, Gamesa.
Continuous casting slab or primary rolling slab is used as raw material, which is heated by stepping furnace, descaled by high pressure water and then enters roughing mill. Roughing material goes through cutting head, tail and then into finishing mill for computer controlled rolling. After the final rolling, it goes through laminar cooling (computer controlled cooling rate) and coiler coil to become straight hair coil.The head and tail of straight hair roll often show the shape of tongue and fish tail, thickness, width accuracy is poor, the edge often exists wave shape, folded edge, tower shape and other defects.Its coil weight is heavy, steel coil inner diameter is 760mm.
